'''Rush Dew Holt, Sr.''' ([[June 19]], [[1905]]–[[February 8]], [[1955]]) was an [[United States|American]] politician who was a [[United States Senate|United States Senator]] from [[West Virginia]] from [[1935]] until [[1941]]. A [[Democratic Party (United States)|Democrat]], he was elected at age 29 in November 1934, making him the youngest person ever elected to the Senate; because a Senator was constitutionally required to be at least 30 years old, he could not take his seat in January 1935 and had to wait until after his next birthday, in June 1935. At the time of his election, he supported [[President of the United States|President]] [[Franklin D. Roosevelt]] and was, in fact, generally considered to be to the [[left-wing|left]] of Roosevelt politically; however, after he was in office, he became a critic of the [[New Deal]]. He was also a staunch [[isolationism|isolationist]], firming opposing any U.S. involvement in overseas warfare at a time when [[World War II]] was beginning. He was defeated for the Democratic renomination in [[1940]] and later became a [[Republican Party (United States)|Republican]]. [http://www.wvculture.org/history/journal_wvh/wvh51-1.html]
